Connect Your Account

ShipEngine API allows you to connect your TNT accounts programmatically without logging in to the ShipEngine API dashboard. This is useful if you have wrapped a custom UI around the ShipEngine API toolset and want to add or disconnect existing carrier accounts without exposing your end users to the API dashboard.

These APIs can be used in parallel with the ShipEngine Partner APIs to programmatically create new ShipEngine users, and then connect existing TNT accounts all via the API without logging into a dashboard. Together these APIs empower you to completely white-label the ShipEngine experience for your end users.

Continue below for instructions on how to programatically connect TNT using the ShipEngine API.

For instructions on connecting TNT via the ShipEngine dashboard, go to our TNT help article.
